"Netiquette" in the game

I am a bloody noob to Monster Hunter. Wilds is my first one and I put 40hrs in it so far. I really, really like this game and I can see myself playing it for a long time :D

I've reached High Rank now and I jump into other peoples missions and SOS Flares since I don't have friends to play the game with.

Is there a "Netiquette" in this game? Things to do and things you should not do while being with other players? I still have this fear of doing something wrong and making people mad :D

Although I come from FFxiv and the community there is really great I must say that the people I met in MH so far are just as nice and welcoming.
